2. How did you spend your summer vacation
I had a busy and interesting summer vacation. I did my homework every day so I finished doing my homework ten days before the new term. I also played table tennis and basketball with my friends every day. I sometimes went movies and went to the parks with my friends. I surfed the internet, read books and watched TV every evening. I visited my grandparents and helped them with the housework, too. I helped my parents clean the room and cook meals. The most important was that my parents and I went to Hannan Island and spent a week there.
